Part Description

LP19739-9   MTHFR gene
The MTHFR gene (methylenetetrahydrofolate reductase (NAD(P)H)) [HGNC Gene ID:7436] is located on chromosome 1p36.3. The protein encoded by this gene catalyzes the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, a co-substrate for homocysteine remethylation to methionine. Genetic variation in this gene influences susceptibility to occlusive vascular disease, neural tube defects, colon cancer and acute leukemia, and mutations in this gene are associated with methylenetetrahydrofolate reductase deficiency.[provided by RefSeq, Oct 2009] [NCBI Gene ID:4524] Two common variants in the MTHFR gene are c.665C>T (also known as c.677C>T, and p.Ala222Val) and c.1298A>C. The 665C>T variant is heat labile, and patients who are homozygous for this variant have higher serum levels of homocysteine and lower levels of folate. Individuals who have one copy of each of the two variants have similar clinical manifestations, while those who are homozygous for 1298A>C do not have elevated homocysteine levels.

Change Reason
Based on LOINC Committee review (June 2016), "targeted" was added to the Component to clarify that this test is looking for a specific set of mutations as described in the LOINC User Guide under the Molecular Genetics section.; Based on LOINC Committee review (June 2019), updated the Property from "Prid" to "Find" and Scale from "Nar" to "Doc" to align with the current LOINC model for naming collections of information reported in narrative and/or structured formats.
